COOKING-RANGE.

Specification of Letters Patent No. 7,946, dated February 25, 1851 Toall whom, it may concern ton, in the county of Suffolk and State ofMassachusetts, have invented certain new in Cooking;

and useful Improvement Ranges; and I do hereby declare that the same arefully described and represented in i the followlng specification andaccompanymg drawings, letters, figures, and references 3 thereof.

F 13, is a rear edge view or elevation of the connectingpiece. Fig. 1 1is a top view of the boiler plate, or that plate of the range which issituated directly over and parallel to the aforesaid top plate of thesaid hot air flue. Fig. 15 is a side elevation of the cast iron fireplace frame. Fig. 16 a back elevation of the oven flue frame.

In the said drawings A represents the furnace or fire place of which Eis the grate and C the ash pit, D the hot wateuback placed directly inthe rear of and formlng in part the boundary of the fire place, Directlyin. rear of the hot water back, is a hot air chamber E, into which thecold air isto be admitted inany convenient manner, and out of which itis to be conducted by a flue space F extending directly under the plate.

G with which the hot water back is to be connected by the. connectingpiece- H to be drawing Figure 1 represents j hereinafter described. Thetop or upper Be it known that I, Mosns POND, of Bosmentioned. From thetop surface of said connecting piece, three or any other suitable numberof plates 6%, e,f, are made to extend horizontally, and to lap or restupon the top surface of the plate G. From the under surface of the upperpart of the said connecting piece, two or any other suitable number ofprojections 6 j, are made to extend under the plate G, the said lates orprojections 6 7, being arranged before described, as projecting from thetop surface of the connecting piece. Similar projections g, 72,, extendfrom the. upper surface of the plate G. There is also between those asimilar one 2'. extended from the lower surface of saidjplate andbetween them on its top surface. The several projections of the topsurface of the plate G where said plate is carried up against theconnecting while the projection from the under side of 1 the plate Gunderlaps the connecting piece, the said projections of said connectingpiece and plate being made so to interlock with each other as to overlapor underlap the joint or line of contact between the connectingpiece andthe plate G so as to closely break or cover the said joint. 1

By inspectionof the drawings of the hot water back it will be perceivedthat ithas two pipes Z, m,entering one endof it, the said pipes beingusually cast in one piece with the water back. i 1

Now as it is often desirable in setting up a range to be able to changeor reverse the water back or to so arrange it that the pipes will passout of it in a direction either to the right or to the left, or from oneor the other endof it, I have provided the water back. withtheconnecting plate and connections by which it may bereversed orturnedI place.

around end for end at pleasure as circumstances may require. It might bethought that the plate Gr could be cast with an inclined fianch to restagainst the beveled part of the water back and to lock under theprojections of such beveled part, and thus entirely dispense with theconnecting piece, and interlocking projections of it and the plate G,but were this the case, it will readily be seen that in order to removea water back at any time for the purpose of substituting another shouldthe first be injured by the fire, or crack by passing of the watertherein, a very common occurrence, it will become necessary to move itdownward and backward, and that this would involve the necessity of notonly cutting away the brick work directly under it or on what it rests,as well as that in rear of its ends or against which they rest; thecutting away of such brickwork is not only extremely diflicult to beeffected, but necessarily occasions a great waste of time and labor,

both in the cutting away and reparation of it.

With my improved connecting piece no depression of the water back isnecessary in order to remove 1t, nor 1S necessary any cutting away ordestruction of the brick work on which its bottom part rests. It may beremoved forwards and horizontally and so as to carry with it theconnecting piece or separate it from the plate G. Again should wedispense with the connecting piece and cast overlapping and underlappingprojections on one side only of the water back, such as are cast on theconnecting piece, it will be readily seen that we can only use the saidwater back in one direction, that is to say; that it would not bereversible as above stated. Consequently from the above it will be seenthat the connesting piece becomes essential as far as convenience and asaving of labor time and expense is concerned.

In the drawing I I represents the oven as placed above and 011 the rightof the fire In Fig. 14 it will be seen that the plate K whichconstitutes the top plate of the cast iron fire place frame I I, is madenot only with a large recess Z along one edge of it, but also anotherand similar recess 112, along its opposite edge, each of said recessesbeing formed by two projections or flanches 92,0, made to extendvertically from the top surface of the plate, and par allel to oneanother, and at a distance apart equal to the thickness of the oven sideflue plate M', the bottom of which is to be placed and made to rest oneither of the said recesses according to the position in which the ovenis placed, either on the right or left of the fire place. If the oven isplaced on the right of the fire place, the flue plate M is so disposedon the left of the oven; if on the contrary the oven be placed on theleft of the fire place, the flue plate M must be disposed on the rightof the oven it being attached in any convenient manner to the ovensupporting and flue frame Q. EX- tending down from both sides of theplate of the fire place frame, are two flue plates 79, 9, through therear part of each of which a flue opening or passage 1 is made. Thus itwill be seen that the fire place frame is provided with two flueopenings, the object of the same being to enable the oven to be arrangedon either side of or to the right hand or left of the fire place ascircumstances may require.

Besides this should it be desirable, it will be seen that suchapplications of two recesses and two flue opening plates admit of twoovens being used in connection with the fire place, one of the saidovens being placed on the right hand of it, while the other is arrangedon the left of it.

I now propose to describe the arrangement of fines by which the smokeand heat are made to circulate around the oven. After passing fromthefire place and through the openings of the fire place frame, thesmoke enters the flue space R situated directly under the left part ofthe oven, thence it passes forward and circulates around the front endof a partition plate S placed directly under the oven, thence passesbackward through a flue T situated under and against the oven, and intoa vertical flue U which is carried upward againstone half of the rearend of the oven, thence into a horizontal flue V carried over thesurface of the oven and to the front thereof thence into anotherhorizontal flue W, which extends rearward over the oven and from thefront to the back part thereof, thence through the damper opening X andthence into the discharge pipe or chimney. Out of the flue which carriesthe heat around the oven, radiating spaces Y, Z, are carried in suchmanner as to allow the heat to circulate from the fines against theupright sides of the oven, as well as against that portion of the backof the oven, against which the flues are not .carried or against whichthey do not directly act, it being usually customary to leave a verynarrow space between the brick work and the back plate of the oven. Thisspace however forms no part of my invention.

The top plate of the oven frame I make with two openings X, A, whichlead respectively out of the fines W, V. A cover B is fitted to one ofthese openings while a sliding damper C is adapted to the other. Bothopenings are to be made of the same size, and so that either the coveror the damper may be applied or fitted'to either of them as the case mayrequire, each being provided with a set of parallel guides D D or E E toguide the movements of the damper when applied to it. When the oven isplaced on the right side of the fire place,

the damper is applied to the opening X,

- sheet iron, and has its bottom platestiifened by a fixed plate E ofcast iron, placed underneath it and riveted to it, this plate does notextend quiteto the front edge of the bot-tom plate of the oven, but ismade to terminate a short distance therefrom and so as to allow the saidbottom plate, when-the oven is in place to rest on the bottom of theopening of the frame or plate F.

In order tomove the oven it becomes necessary to raise it upward alittle before it can be drawn out of the frame by which it issupported,so inorder to admit of its beingraised up. The partition which dividesthe flue V from the flue W, has a sliding plate Gr aflixed to it, bymeans of such contrivances as will not only hold it against thepositions, but admit of its being raised or lowered or allowed to slidefreely up or down, and to drop by its own weight and rest upon the topof the oven, so as to make a close joint when the oven is in place. Onraising up the oven in order to remove it, the plate (G) will readilyrise upward with it and admitof its being removed. It also permits theoven to be readily inserted in a place and by dropping down upon theoven 40 prevents the smoke from passing from over flue V under thepartition and into the other flue W. The regular flue passages aroundthe oven are carriedin contact with the bottom part thereof, one half ora portion of the back part thereof, and the top thereof, they in norespect are intended to lead the smoke and volatile products of combust-ion against the sides of the oven, such side'of the oven beingheated by the heat that passes from underneath the oven and into thefines or spaces which are made directly against the said sides of theoven.

What I claim as my invention is 1. The improvements by which thehotwater back is connected with the plate G and by means of which saidhot water back may be either readily removed at any time, or applied insuch manner that the directions ofits water pipes may be disposed so asto accommodate the bath boiler into which they are usually led, onwhatever side of the range the said bath boiler may be placed. The saidimprovements consisting first, in the connecting piece H and theattachments of it and the hot Water back, the whole being made to.operate together, substantially in the manner as above set forth.Second, in asecond set of attachments (fixed on the opposite face of thewater back) in combination with the. first set thereof, as described. i

2. I also claim the peculiar arrangement of fiues which lead the smokeand volatile ward and over and against the top of the oven and conveysit to the chimney or discharge fiue. Not meaning to include in sucharrangement the radiating chamber or space Y, Z, hereinafter mentioned.

3. And I also claim the two recesses Z, m, and two flue plates, 12, 9,applied to the plate K in combination with the two valve openings X, A,thin damper and .cam plate as applied to the top plate of the oven frameand used under an. arrangement of oven flues substantially as described,the same a1- lowing of 'the adaptation of the oven to either-side of thefire place, or the use of two such ovens and their frames, in connectionwith the fire place, all essentially as hereinbefore stated.

4. I also claim the improvement by which the oven can be raised andreadily removed, and by which the smoke is prevented from passingunderneaththe partition which separates the flues. on top of theoven thesame consisting in the sliding or gravitating plate G, aifixed to thepartition and made to operate substantially in the manner as specified.

In testimony whereof I have hereunto set my signature,thistwenty-thirdday of. September, A. D. 1850. y
